Abstract

The invention relates to a super-hydrophobic antifouling ceramic tile which is characterized in that the surface of the ceramic tile is coated with a super-hydrophobic fluorosilicone resin ceramic antifouling agent by about 1-2g / cm < 2 >, and the super-hydrophobic antifouling ceramic tile is obtained. According to the super-hydrophobic fluorosilicone resin ceramic antifouling agent, perfluoro hydrogen-containing polymethylhydrosiloxane is used as matrix resin, amino-substituted polyhedral oligomeric silsesquioxane and polyisocyanate are used as cross-linking catalysts, and nano aluminum oxideis used as reinforcing filler so that the super-hydrophobic fluorosilicone resin antifouling agent which is cured at normal temperature is generated. The super-hydrophobic antifouling ceramic tile issmall in glossiness influence, excellent in hydrophobicity and good in antifouling effect.

Description

technical field [0001] The invention relates to a ceramic brick, in particular to a super-hydrophobic antifouling brick, and belongs to the technical field of hydrophobic and antifouling bricks. [0002] technical background [0003] During the firing process, the ceramic tiles will absorb pollutants due to the pores and tiny cracks remaining on the brick or glazed surface. The current ultra-clean and bright ceramic tiles can solve the above problems by adding antifouling agents to fill the holes during polishing. At present, the best anti-fouling for ultra-clean and bright tiles at home and abroad is nano-anti-fouling, that is, a layer of nano-scale protective layer with special protective function and stable structure is formed on the edge of polished tiles and glazed tiles. It is mainly used to upgrade ceramics. The anti-fouling performance of polished tiles is known as a revolutionary breakthrough in anti-fouling technology in the building ceramics industry, and it also g...
